In the 1930s, Potsdamer Platz was one of the most bustling places in Europe. It was wiped out during the Second World War and later transformed into a death zone of the Berlin Wall. Nowadays it’s the new, corporate-branded heart of modern Berlin. At the entrance to the Sony Center you will find a fragment of the former Grand Hotel Esplanade – the so-called "Kaisersaal" (Emperor’s Hall) had been dislocated 75 meter far in 1996 using air buffer.
